Can anyone suggest some stuff to play on the guitar? I'm hacking out the same tunes day in day out, and sort of run out of inspiration. What I'm looking for is some tunes that are recognisable and sound good on an acoustic. Could be anything from a famous Elvis song to a classical piece. I suppose what I'm saying is can the gutarists out there post their favourite tunes to play..........or the chords if its a simple one.
I can start - my current projects include:
Classical Gas - Eric Clapton
Classical Version of Bohemian Rhapsody
Moonlight Sonata and Canon in D.
Perfect Day - Lou Reed.

I thought you were thinking instrumental "show off" type stuff. If you mean SONGS to play and sing, damn, there are hundreds dude! Take your pick, most classic well known songs are pretty simple as far as chords go. To make it sound good to don't need to do anything fancy, just get rock solid in time, which can be done by hours and hours of playing along with a metronome, about 4 hours a day for 5 years should do it ...

PS Bob Marley songs are a winner on guitar if you can sing along too ...

Here are a few suggestions for nice little tunes to play. 'Little Wing' and 'The Wind Cries Mary' by Hendrix are great little tunes. 'Tears in Heaven' by Clapton is a nice little simple tune. Any tune by the genius Pierre Bensusan is great, though some of them are really tricky, DADGAD tuning is great fun for plonking around.

Bouree in E minor by Bach is a great little tune. A lot of Beatles stuff is great for playing on the guitar, 'Something', 'Blackbird' as mentioned, 'Let It Be'. Too many great Beatles tunes to mention.

I like to use alternate tunings a lot and there are some great little Irish reels and things that you can play in DADGAD tuning. I cant remember the name of the book I bought a few years ago but it is a great introduction to using DADGAD and playing Irish music.

For classical stuff, you cannot go wrong with Leo Brouwer's 20 "Etudes Simples". Short, simple, and sound great. Whenever someone puts me on the spot and asks me to play something for them, I usually go for one of those. I think they're practically mandatory in most first year classical guitar courses.
Also one of my personal faves is "Popular Classics of the Great Composers" by Jason Waldron (in 6 volumes). Any great classical work you can think of transcribed for solo guitar! With an accompanying C.D!

Some nice tunes to play down on the acoustic, pardon for not being as esoteric as some of the choices here, but these will be mainly recognisable... :)

Eric Clapton's Tears in Heaven sounds great while being very easy to play. Highly recommended early on as it's great motivation :)

Richard Marx - Now and forever
Extreme - More than words
Metallica - Nothing else matters
RHCP - Soul to squeeze
3 Doors Down - Here without you
Goo Goo Dolls - Iris. This one requires some arsey tuning, and doesn't sound right without a banjo, or the right strings. Worth a shot, especially if you can sing along with it, as it's one of my faves.. :)
Incubus - Drive
Michelle Branch - Everywhere
Puddle of Mudd - Blurry (grab the acoustic version, tuned down). This is great practise for your harmonics, and sounds great if you have a buddy to play with. Ambitious, but get it down, and it's a lot of fun.
Sheryl Crowe - Strong enough
Jack Johnson - Flake
Seether f. Amy Lee - Broken. New single from the Punisher movie. The movie is crap, but this song is great to play.

Hope you liked these choices. Not sure if they're your cup of tea as they're comparatively commercial.
